The National Archives in the UK have a fairly active flickr-account where they post interesting photos and documents from their popular archives. Here is an interesting document from the British Embassy in Mogadishu, Somalia, dated 4th of September 1968, stating that «almost anything is of interest to somebody»:

Dear Library,

We found the enclosed photographs in the former Consulate-General at Hargeiss. They are of administrators of British Somaliland. There was one more, of Sir Harold Kittermaster*, but it was too mildewed to be taken from its frame.

2. Believing that almost anything is of interest to somebody, and in case there is no other record of these particular faces, we send them to you. If they are of no interest please throw them away and forgive us the trouble we have cause you.
